RING FOR SPINNING MACHINERY,

Providence and State of Rhode Island, have invented certain new and useful Improvements in Ringsfor Spinning Machinery, of

which the following is a specification.

.My invention, while relating to rings for spinning machinery generally, has reference more particularly to that form thereof in which the rings are rotatively mounted upon the ring, rails, and effect the twisting of the yarn or thread and its winding upon the spools or bobbins by their rotation, as shown,

for instance, in U. S. Letters Patent 'No. 759,846, which were granted to Abel T. Atherton and myself, May 17th, 1904. In rings of this class, as heretoforeconstructed,

have usually been formed has been eit the wear incident to their use, has had to be case or otherwise hardened. As a consequence of this, the rings in the hardening operation have been more or less sprung .or distorted and thereby thrown out of symmetry, with the result that the center of mass of each has been carried to one side of "*its axis of rotation, or into eccentricity thereto, which defect has occasioned more or less wabbling and gyrations in the ring when in rotation, with the consequent strainin and friction of the parts, accompanied wit the p breakingof the yarn or thread and the for mation of large and small places and other imperfections therein. objections, it has been the custom to grind the rings after the hardening operation, to

properly balance them and bring their parts into concentricity with the axes of their rotation, but this, while effecting the truingup of the rings in a measure, has been found expensive in practice, and when applied to 4 5. rings that were only case-hardened the grind ing fro uently cut through the case-hardened shell, t ereby exposing the unhardened portion beneath it, with the result that when 7 these exposed unhardened portions appeared in alternation with the hardened portions in. the tracks through which therings are sup ported from the rails, they have worn un- Specification of Letters Patent.

er wrought V iron or steel, which, in order to withstand To ,obviate these Patented Dec. 10,1907;

equally and thereby presented rough and uneven surfac'eson the tracks for-contact with the rolls through whichthe support of the rings from their supporting rails is effected.

The ob'ect of the invention is therefore to obviate this-objection, and to produce a-ring .of this class, which, While permitting of the hardening of the track throughwhich the ring is supported and its subsequent grinding to bring itinto symmetry, shall, at the same time, dispense with the necessity of,

hardening the remainder f" the ring, and

thereby permit of-the us of- -a cheaper mate rial in its construction.

To these ends,.- the-invention consists in.

certain peculiaritiesofcdnstruction whereby these and other and:furtheradvantagesare attained,- all as will hereinafter more fully ap ar.

A indicates a rail or other appropriate support, which is or may be of-any ordinaryor preferred construction, and B indicates a ring which-isrotativel mounted thereon; The means by which th ring uponthe railis efiected ma be of various kinds. In the drawings, owever, I have shown them as consisting of a plurality of rolls a, which are disposed at suitable dis- 7 tances apart around the rings, and are journaled in stands a, that are adjustably or otherwise secured to the rail or support A by screws 0, and a The rail or support A, wi

invention is employed and, while the rail or support A has been shown as made of a length to receive but a single ring, with the ring-mounting appliances, it is to be understood that in ractice the rail or support may be made of a liength to accommodate either a single ring, or a plurality of rings. The ring. B may, in like manner, be constructed in various forms, but however constructed the track I), by which-the ring is mounted on the rail or support A is made in'a separate iece, in the form of an annulus, and is detac ably secured thereto. As shown in the drawings however, this ring is constructed in a cylindro-tubular form, and, provided with a thread-guide or guides at its 11 er end, and

ove d below for receiving the driving-band (not shown), by which its rotation is effected, is also equi ed upon its depending annular portion wit a supporting track I), which is secured to its lower end. In some instances, the track I), may be constructed as an outwardly extending-surface for engagement with appropriately shaped grooves 11 formed in the rolls a, while in others it may be formed in the shape of a groove, and the peripheries of the rolls so shaped as to engage with it, as shown, for instance, in Fig. 4. I prefer however to construct it in the form in cross-section of an outwardl projecting V shaped surface, and to form the grooves a in the rolls a/of a contour to correspond to it. As thus formed in either of the ways specified, the track is preferably constructed of steel or other ap ropriate material that admits of being ardened, while the body or remaining portion of the ring may be made of the same or other materials. I prefer however to construct this body portion of either wrought-iron or cast-iron, and to secure the track thereon, latter has been hardened and ground to bring it into symmetr The means by which this securement of t e track to the body, or to the remaining portion of the ring, is effected, may be of various forms. In Fig. 2, I have shown its securement in place accomplished by forcing the track upon the ring, and holding it thereon by frictlon; while in Fig. 3, I have shown it as secured in place by screw threads, with which its interior and the exterior of the body of the ring are provided, but these forms of securement are merely illustrative and other forms may be adopted in place of them if so desired.

With the ring'constructed as above explained, its body may, as before remarked, be made of the same or ofa different material from that of which the track is formed but left unhardened, with the result that no subsequent grinding of the same is necessary,

whlle the track, which is really the only part that is subjected to wear, be hardened either on the surface or throughout, and only the grinding of this portion of the ring required to properly bring it and the other parts of the ring into balance and concentricitywith is axis of rotation, and which said grinding may be effected without endangering in any way the cutting through of the hardened shell, as frequentl happens with the case-hardened rings 0 this class as hitherto constructed.

Such being the characteristics of my ring, it will be seen that I not only cheapen the cost of construction thereof,but I also produce a ring which possesses many marked advantages, since, in consequence of making the trac b detachable and ina separate piece, the necessity for hardening the body portion of the ring and thereby the throwing of the same out of symmetry, with the con sequent requirement for subsequent grinding to bring itback into 0 ncentricity with its axis of'rotation, is obviated, and the use of a cheaper material in the formation of the same permitted; while the track itself instead of being only case-hardened, may be hardened throughout and thereafter ground to bring its parts into symmetry before being applied to the body of the ring, without cutting through the hardened surfaces thereon, which severalresults are of the greatest ind-- portance when the vast number of ii s required in the textile spinning and twisting operations are considere With the ring constructed as above de-- I scribed, there may be employed any of the ordinary forms of thread-guides heretofore in use, whether formed by slitting the upper edge of the ring, or by securing hooks thereto, but these form no part of my present invention, and areormay be the same as those shown at a} a and a in the Letters Patent aforementioned. Y I

While in the foregoing I have described my rings as ap licable to spinning machines, it is to be un erstood that they are not resfiricted in their use thereto, as it is obvious t at withtwisting and other analo ous forms of machine and operate with equa efficiency.

Having now described my invention, and specified certain of the ways in which it is or may be carried into effect, I claim and desire to secure by Letters Patent of the United States,-
